Caution
This instrument is intended to be used under the following environmental conditions
(IEC61010-1): Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:
• A minimum of dust, and an absence of corrosive gases
• No flammable, explosive gases
• No mechanical vibrations or shocks
• No exposure to direct sunlight, an ambient temperature of -5 to 55 (23 to 131 )
that does not change rapidly, and no icing
• An ambient non-condensing humidity of 35 to 85%RH
• No large capacity electromagnetic switches or cables through which large current is flowing
• No water, oil or chemicals or where the vapors of these substances can come into
direct contact with the unit
• When installing this unit within a control panel, take note that ambient temperature of
this unit must not exceed 55 (131 ). Otherwise the life of electronic components
(especially electrolytic capacitor) may be shortened.
Note • Do not install this instrument on or near flammable material even though the case of
this instrument is made of flame-resistant resin.

Caution
• Do not leave bits of wire in the instrument, because they could cause a fire and malfunction.
• When wiring terminals, use ferrules with an insulation sleeve and crimping pliers made
by Phoenix Contact GMBH & CO. applicable to terminals.
• Tighten the terminal screw using the specified torque.
If excessive force is applied to the screw when tightening, the screw or case may be
damaged.
• This instrument has no built-in power switch, circuit breaker or fuse. It is necessary to
install them near the instrument.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)
• For wiring of AC power source, be sure to use exclusive terminals as described in this
manual. If AC power source is connected to incorrect terminals, the unit will burn out.
• For a 24V DC power source, do not confuse polarity when wiring.
• Do not apply a commercial power source to the sensor connected to the input terminal nor
allow the power source to come into contact with the sensor, as the input circuit may burn out.
• Use a thermocouple, compensating lead wire and 3-wire system RTD according to the
sensor input specifications of this unit.
• When using DC voltage and current input, do not confuse polarity when wiring.
• Keep the input wire (TC, RTD, etc.), power line and load wire away from one another.

Caution
• Do not touch live terminals. This may cause electric shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal and
cleaning. Working or touching the terminal with the power switched ON may result in
severe injury or death due to Electric Shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)
• As the display section is vulnerable, do not strike or scratch it with a hard object or
press hard on it.
